Also I am asked why you use this complicated tcl parameters.
NS, by default, has the
data rate for the MAC set at 2 Mbps. But cards are faster now. My
cards are 802.11b, which means they're 11 Mbps, and so we need to
change this. Add the following to the beginning of your simulation
script:
hi all,
i am confused by the bandwidths when i am wirting a wireless 802.11 scenario.
there are many bandwidths and rates:
LL::bandwidth_
Mac::bandwidth_
Phy::bandwidth_
Mac802_11::basicrate_
Mac802_11::datarate_
I don't know what are the differences between them? when to use them?
Could
Data link Layer contains the two units(LLC,MAC) as structure So
LL::bandwidth_ refer to the bandwidth of Logical Link layer
Mac::bandwidth_ refer to the bandwith of Media access layer
Phy::bandwidth_ refer to the bandwith of physical layer
Mac802_11::basicrate_ //Rate for Data Frames
